a: The expression of anti-inflammatory (EP3, IL-1ra) and proinflammatory (IL-1β, IL-6, MIP-2, and MPO) cytokines in control and MSCs transplanted lung parafin sections. The expression levels of EP3 and IL1ra (membranous) were increased in the tissues of rBM-MSCs group with respect to those of the control group. In contrast, the expressions of proinflammatory cytokins, IL-1β, IL-6, MIP-2 and MPO were reduced in rBM-MSCs group. b: The number of cells expressing proinflammatory cytokines (IL6, MIP-2, MPO and IL-1β) decreased in the group transferred with MSCs compared with control group (*p < 0.05, **p < 0.01)
